METHOD OF PUTTING UP METAL-FOIL PACKAGES.

SPECIFICATION forming part of Letters Patent No. 471,609, dated March29, 1892. Appli ation fil d llovemher 25,1891. SerialNo. 413,047. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN H. J. HAINES, a citizen of the United States,and a resident of Flushing, in the county of Queens and State of NewYork, have invented a certain new and useful Method of Putting UpMetal-Foil Packages, of which the following is a specification.

Myinvention relates to an improved process of putting up packages oftobacco or other substances in metal-foil wrappers, and is designed asan improvement upon the processes heretofore employed, wherein theWrapper is folded around a suitably-shaped funnel with the edges of thewrapper overlapping, and the substances are afterward introduced intothe funnel and the latter afterward withdrawn.

Heretofore it. has been the practice in order to make a secure packageto allow avery considerable overlap of the edges of the wrapper uponthefunnel. Owing to the extent of this overlap, a great deal of surplusmetal foil beyond that which would be necessary to simply inclose thepackage in foil is required for each package.

The object of my invention is to economize in the use of foil and at thesame time obtain a package which shall be practically as secure, and, infact, more secure, than those produced by the ordinary process.

In carrying out my invention in the putting up of tobacco or othersubstances in tinfoil packages I wrap the tin-foil around the ordinarypacking-funnel with the edges of the sheet-metal foil slightlyoverlapping one another asufficient distance only to permit the one edgeto be fastened upon the other and then apply the pressure of a suitableheated tool to the surface of the foil where it is lapped. In thisoperation the funnel forms a solid backing, which prevents injury to thefoil in the operation of applying the pressure. It will be obvious thatby this procedure the packages can be much more expeditiously made thanby the plan which'has been here tofore proposed of making up metal-foilpackages the edges of which are soldered together overa paper wrapperand the wrappers afterward slipped upon the funnel.

My invention is of especial utility in the putting up of tobacco orother substances in foil-wrappers after the manner ordinarily employedof folding the wrapper around the funnel and then filling the package,because I am able to reduce very materially the extent of overlap of thefoil edges, which has heretofore been necessary and can therefore savelargely in the material.

The drawingillustrates the manner of practicing my invention, the funnelupon which the wrapper is wound for filling being shown in perspective.

The tool A resembles in general form the soldering-instrument at presentin general use; but the point is blunted or rounded at its lower endwhere it engages the foil.

The tool A may be mounted on a-suitable fixed support, or it may beadapted to be held in the hand, as well understood in the art. The lowerend of the tool, or the pressurepoint thereof, as indicated at E, isblunt or rounded to prevent cutting 0E or injury to ferent from theordinary forms of solderingtool, which have a rather sharp point thatin. practice would be found entirely unsuitable for uniting metal foil,because it would tear or injure the foil. I prefer to make the point Efrom iron, steel, nickel, or similar material which 'Will not readilyamalgamate with tin, as does the ordinary copper. I by this meansobviate the danger of the pressure-tool when highly heated wiping awaythe metal foil or the coating thereof when the pressure is applied, ashereinafter described, and the foil sheet is run along under the pointwith pressure.

F indicates the ordinary packers funnel as employed in putting uppackages of tobacco. The tin-foil wrapper or the paper and tin-foilWrapper is applied, as well understood in the art, by Wrapping it aroundsaid funnel and the end folded down, after which the material isintroduced into the funnel in proper amount and the latter is thenwithdrawn.

In practicing my invention the edges of the.

tin-foil wrapper are overlapped upon the side of the funnel a distanceindicated by the full and dotted lines, and then the lapped portion ispressed down by means of the heated'pressthe foil, and in this respectis essentially difure-tool, thus uniting thetwolappedsurfaces Where theyare in contact firmly together by the action of the heat communicatedfrom the tool through the outer metal sheet, combined with the pressure.The pressure is applied by applying the foil at its lapped portion Whileupon the funnel to the tool E and moving it. along against said tool inthe line of the joint, the funnel with the wrapper being pressed upwardrather firmly against the heated tool. In this operation the funnelforms a solid backing, which prevents injury to the foil. The projectingend of the Wrapper may be folded down upon the end of the funnel eitherbefore or after the operation just described. An overlap at the edges ofabout one-eighth of an inch Will be found sufficient for all practicalpurposes.

It will be obvious that in practicing my invention the tool might bedrawn along over the su'rface of the tin-foil sheet at'the part where Iit overlaps the other sheet, pressure being applied to a suitable degreeat the same time.

WVhat I claim as my invention is The herein-described improved processof putting up metal-foil packages, consistingin Wrapping the sheet-metalfoil around the filling-funnel with its edges overlapped, then pressingthe lapped portions together by a heated pressure-tool applied to theouter surface, and afterward filling the package through said funnel,the foil-wrapper soldered on said funnel being retained in place thereonfor that purpose, all as set forth.
